We all know that AppleCare is the channel to use to notify about issues. The problem is that, as you have seen, the issue is subtle and in most case is not replicable in the shops. Anybody who tried opening an AppleCare ticket got their laptop taken, airport replaced, just to have the problem again afterwards.
To a certain degree that's also helpful as it helps Apple rule out whether it's a hardware issue with their systems or not. This is how Apple both finds out about true hardware issues as well as finds things ranging from bad chip runs by vendors, improper installation of AirPort cards at the factory, failure to connect or pinched antenna cables, etc.
Apple engineering will also occasionally "capture" a problematic user machine for their own diagnostic purposes to try and reproduce the issue in-house. Working with captured machines only to find no issues with them in-house is also a major data point that points toward either a router issue or a software problem.
Regardless, none if it can occur without going through AppleCare first.
The only way to get Apple to understand this is real, is to bring one of their engineers in one of the environments where the problem takes place.
Possible, but there are far too many variables involved to do that. I can't say that they won't do that, but even if they do it will be by contacting someone who has reported the problem to AppleCare.
Apple doesn't have "field service" techs per se, so I suspect highest priority would be given to someone experiencing the issue that happens to live in Cupertino. 😀
As you suggest, I would contact AppleCare just for the sake of it, but which computer will I use in the meantime? I have already spent $2,000 for the first MBP, shall I spend another $2,000 for a backup one, while leaving the first to Apple? And if they don't find anything, as it usually happens, I shall bring it back again and again and again?
In general Apple won't have you send it back in if the problem persists after a repair.
If your system needs to be captured for engineering, they may be nice enough to cross-ship you a new one.
The fact that all other PCs and wifi devices I have work nicely is a proof of the fact that it is not an environmental issue, nor a router one.
That simply is not true. The biggest fallacy people have is to say "these devices all work, the Mac is at fault" when in reality that is not a valid test.
The example I like to give is if there's a bug in the firmware where adding "3 + 2" returns 5 but adding "2 + 3" returns 6.
If Windows PCs and other devices always add "3 + 2" but the driver for the new MBP happens to add "2 + 3" and gets an incorrect answer from the router, it's not Apple's responsibility to work around that, it's the router manufacturer's responsibility to fix their issue.
You say it's not hundreds of users, but I would not be so sure. There are several threads describing sometimes in different ways the same issue, for the latest and the previous generation of MBP.
Just by scanning AD, I'd say the number of reports is well under 100.
Now please, don't for a minute believe I am trying to downplay the issue or how frustrating it is for you.
Rather I'm trying to point out that going through AppleCare is the only way this issue will get resolved.
Apple engineering is who has to diagnose and resolve the issue, and the information you provide to AppleCare is the only way they get the data to be able to do that.
